Abstract: PURPOSE:To make the main body case firm, and to prevent the air leakage caused by damage of a dust collecting chamber and the deformation of the main body case caused by a pressure variation of the dust collecting chamber by constituting the dust collecting chamber of a double wall and forming an exhaust passage. CONSTITUTION:A side wall and a bottom part of a dust collecting chamber 21 for containing a dust collecting bag provided in front of a main body case 20 are formed by a hollow double wall which becomes a dust collecting chamber side exhaust passage 22, and a reinforcing rib is provided between the double walls. Also, it is desirable that a caster fitting seat formed by superposing the double walls having no hollow part is formed in a part of the bottom part. In a motor chamber 25 which is provided on the rear part of the main body case, and in which a fan motor is contained, a motor side exhaust passage 26 is formed so that exhaust air from an exhaust port 5 of a motor 2 communicates with the dust collecting chamber side exhaust passage 22 formed by the double wall, and in the main body case which becomes the front part of the dust collecting chamber, an exhaust outlet 27 for communicating with the dust collecting chamber side-exhaust passage 22 is provided. According to this constitution, even if the inner wall of the dust collecting chamber is deformed by pressure applied to the inner wall of the dust collecting chamber, deformation of the main body case can be prevented by the hollow part. Also, since the exhaust passage can be lengthened, a noise can be lowered.

Title: Image reader
Inventor: KUSUMOTO HIROSHI
IPC: G03B27/50
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To provide an image reader with which processing speed can be easily prevented from being decelerated. SOLUTION: The moving velocity of a carriage 11 is first accelerated to velocity v2 higher than reading velocity v1 within the approach run range from start at a home position 19 to arrival at a reading start position 18. Afterwards, the moving velocity is decelerated and becomes the reading velocity v1 in the approach run range. After the carriage moved in the remaining approach run range and an image reading range in the state of velocity v1, it returns to the home position. Thus, the moving velocity of the first carriage 11 is high in comparison with the conventional example until it arrives at the reading start position 18, at the time of repeat copy, processing speed is accelerated.

Filed: 1985-10-29
Abstract: PURPOSE:To prevent the performance of a liquid crystal cell from deteriorating by forming gaps between both polarizing beam splitters and the liquid crystal cell and forming a transparent elastic member so that the gaps are filled with the member. CONSTITUTION:The gaps 21 with width D are formed between the liquid crystal cell 7 and the polarizing beam splitters 6, 8 and the liquid crystal cell 7 is held by a holding body 23 so that the gaps 21 are filled with the holding body 23. The holding body 23 has approximately the same refractive index as that of glass bases 11, 12 of the cell 7 and that of a glass material for the beam splitters 6, 8 and consists of a sol-like medium with high transparency and elasticity. The width D is larger than the expansion width of the cell 7 obtained when the cell 7 is most expanded by the increase of temperature. Consequently, the expanding/contracting deformation of the liquid crystal cell 7 due to temperature change is absorbed by the elastic member, so that the performance of the liquid crystal cell 7 can be prevented from deterioration and the quality of the liquid crystal cell 7 is improved.
